IMPROVED FLOUR-COOLER.

The Schedule referred to in these Letters Patent andrmaking part ofthe same.

To all ywhom it may concern:

Be it known thatlI, W. W. Gern, of Avoca, in the county of' Steuben, and State of N ew York, have invented certain new and useful Improvements in a Flour-Cooler; and I do hereby declare that the following is a full, clear, and exact description thereof, referencev being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciiication, in which- Figure l represents a side elevation of my machine.

Figure 2 is an end view of the saine.

The nature of my invention consists-in the construction of a machine for cooling ilour after it leaves the stones, and before it reaches the bolt.

To this end, I construct two Cylinders on the same shaft, the inner being largest at the end from which the iorrr is discharged, the sa-id cylinder receiving the flour by means of a conduit inserted in its small end.

My invention further consists in supplying the space between the two cylinders with a current of cold' air, by means of a blower, in the manner hereinafter fully described.

A represents the main cylinder, which is connected with -the shaft B by means of arms l d, which are at- Both cylinders are fastened together at their ends.

The shaft B is supported at its end by luprights f and g.

e e designate a series of curved metal plates, fastened at one edge to the end of cylinder' A, and at the other edge secured to iiange Gr. rlhe plates c e are sufticiently far apart'at their outer ends, and approach open end of cylinder (l. y

- l1y represents a trough,'one end of which is fastened to upright g, and the other enters the open end of cylinder C, t-lrrouglr a hole in the end of cylinder A.

The ends of shaft S are supported by brackets fasterred to the sides ofthe blower H.

'I he shaft S is furnished with the pulley J, by which it is operated.

The blower H is kept in its proper position by the stanchion D.

It will be observed that cylinder A has a number of perforations, t, near the end from which the flour is discharged. 'lhe object of these pertbrations is to Vent theair after it has performed its function of cooling the external surface of cylinder C.

nis the spout, through which the our is conveyed to the bolt.

Havingthus described my invention,

What I claim, and desire to secure byLetters Patent, is

1. 'lhe blower H, in combination with curved plates c e, when constructed, arranged, and operated as described.

2. Cylinders A and O, when combined'with blower H, curved plates e c, and conduits hand n, the whole arranged and operating substantially as described.

In testimony that I claim the foregoing as my own, I afiix my signature, in presence of two witnesses.
